Winter Fuel Tips

WINTER BLENDING WITH BIODIESEL
• Splash blending of neat biodiesel (B100) with petroleum diesel should occur when both products are 40 degrees F or above.
• Low blends (B2 or B5) typically have very similar (within 0 to 5 degrees) Cloud Point and CFPP characteristics to conventional diesel products and can be treated in a similar fashion to #1 blend.
• Animal fat and higher level soy blends may increase the CFPP of the fuel as much as 5 degrees for every 10% of B100 used.
AST (Above Ground Storage Tanks)
Drain and remove all water and contaminants
Change filters and clean pump screens
Pre-blend #1 with existing fuel (blended above cloud point) as needed for your climate
Consider use of Winter Additive in existing fuels (packaged Winter Additive available from Lubricants dept)

Winter Fuel Blending
When blending fuel always remember that the fuel, biodiesel and additives must be 5-10 degrees above their cloud point. If you are unsure what the cloud point of the fuel is then contact MVP.
A rule of thumb when blending #1 fuel is every 10% of #1 fuel will reduce cloud point of the blended fuel by 2 degrees F. Keep in mind the only thing that will reduce the cloud point of #2 fuel is adding #1 fuel.
Ex: A #2 meeting cloud point spec (14 F degree cloud point) blended with 10% #1 will yield a 12 degree F cloud point. A 50-50 blend will yield a 4 degree F cloud point (14F –10F).

*CFPP (Cold Filter Plugging Point) is the temperature at which wax crystals will plug a fuel filter.
Note: MVP believes the CFPP test is not as reliable as it once was due to changes in the fuel with the advent of ULSD and tighter filtration on newer equipment. You shouldn’t rely on cold flow additives to drop the filter plugging point of the fuel more than 15 degrees from the cloud point (cloud point minus 15 degrees F).
Thanks for your diesel fuel business and we look forward to meeting your winter fuels needs during the coming season!
